Both are commonly used to make ++preparations before the real root file system can be mounted. ++ ++== Rationale ++Many Linux distributions ship a single, generic kernel image that is intended to ++boot as wide a variety of hardware as possible. The device drivers for this ++generic kernel image are included as loadable modules, as it is not possible to ++statically compile them all into the one kernel without making it too large to ++boot from computers with limited memory or from lower-capacity media like floppy ++disks. ++ ++This then raises the problem of detecting and loading the modules necessary to ++mount the root file system at boot time (or, for that matter, deducing where or ++what the root file system is). ++ ++To further complicate matters, the root file system may be on a software RAID ++volume, LVM, NFS (on diskless workstations), or on an encrypted partition. All ++of these require special preparations to mount. ++ ++Another complication is kernel support for hibernation, which suspends the ++computer to disk by dumping an image of the entire system to a swap partition or ++a regular file, then powering off. On next boot, this image has to be made ++accessible before it can be loaded back into memory. ++ ++To avoid having to hardcode handling for so many special cases into the kernel, ++an initial boot stage with a temporary root file system ++—now dubbed early user space— is used. This root file system would contain ++user-space helpers that would do the hardware detection, module loading and ++device discovery necessary to get the real root file system mounted. ++ ++== Implementation ++An image of this initial root file system (along with the kernel image) must be ++stored somewhere accessible by the Linux bootloader or the boot firmware of the ++computer. This can be: ++ ++* The root file system itself ++* A boot image on an optical disc ++* A small ext2/ext3 or FAT-formatted partition on a local disk ++ (a _boot partition_) ++* A TFTP server (on systems that can boot from Ethernet) ++ ++The bootloader will load the kernel and initial root file system image into ++memory and then start the kernel, passing in the memory address of the image. ++ ++Depending on which algorithms were compiled statically into it, the kernel can ++currently unpack initrd/initramfs images compressed with gzip, bzip2 and LZMA. ++ ++== Mount preparations ++dracut can generate a customized initrams image which contains only whatever is ++necessary to boot some particular computer, such as ATA, SCSI and filesystem ++kernel modules (host-only mode). ++ ++dracut can also generate a more generic initramfs image (default mode). ++ ++dracut's initramfs starts only with the device name of the root file system (or ++its UUID) and must discover everything else at boot time. A complex cascade of ++tasks must be performed to get the root file system mounted: ++ ++* Any hardware drivers that the boot process depends on must be loaded. All ++kernel modules for common storage devices are packed onto the initramfs and then ++udev pulls in modules matching the computer's detected hardware. ++ ++* On systems which display a boot rd.splash screen, the video hardware must be ++initialized and a user-space helper started to paint animations onto the display ++in lockstep with the boot process. ++ ++* If the root file system is on NFS, dracut does then: ++** Bring up the primary network interface. ++** Invoke a DHCP client, with which it can obtain a DHCP lease. ++** Extract the name of the NFS share and the address of the NFS server from the ++lease. ++** Mount the NFS share. ++ ++* If the root file system appears to be on a software RAID device, there is no ++way of knowing which devices the RAID volume spans; the standard MD utilities ++must be invoked to scan all available block devices with a raid signature and ++bring the required ones online. ++ ++* If the root file system appears to be on a logical volume, the LVM utilities ++must be invoked to scan for and activate the volume group containing it. ++ ++* If the root file system is on an encrypted block device: ++** Invoke a helper script to prompt the user to type in a passphrase and/or ++insert a hardware token (such as a smart card or a USB security dongle). ++ ++* Create a decryption target with the device mapper. ++ ++dracut uses udev, an event-driven hotplug agent, which invokes helper programs ++as hardware devices, disk partitions and storage volumes matching certain rules ++come online. This allows discovery to run in parallel, and to progressively ++cascade into arbitrary nestings of LVM, RAID or encryption to get at the root ++file system. ++ ++When the root file system finally becomes visible: ++ ++* Any maintenance tasks which cannot run on a mounted root file system ++are done. ++* The root file system is mounted read-only. ++* Any processes which must continue running (such as the rd.splash screen helper ++and its command FIFO) are hoisted into the newly-mounted root file system. ++ ++The final root file system cannot simply be mounted over /, since that would ++make the scripts and tools on the initial root file system inaccessible for any ++final cleanup tasks. On an initramfs, the initial root file system cannot be ++rotated away. Instead, it is simply emptied and the final root file system ++mounted over the top. ++ ++= User Manual ++ ++== Creating an initramfs Image ++To create a initramfs image, the most simple command is: ++---- ++# dracut ++---- ++ ++This will generate a general purpose initramfs image, with all possible ++functionality resulting of the combination of the installed dracut modules and ++system tools. The image is /boot/initramfs-_++++_.img and ++contains the kernel modules of the currently active kernel with version ++_++++_. ++ ++If the initramfs image already exists, dracut will display an error message, and ++to overwrite the existing image, you have to use the --force option. ++---- ++# dracut --force ++---- ++ ++If you want to specify another filename for the resulting image you would issue ++a command like: ++---- ++# dracut foobar.img ++---- ++ ++To generate an image for a specific kernel version, the command would be: ++---- ++# dracut foobar.img 2.6.40-1.rc5.f20 ++---- ++ ++A shortcut to generate the image at the default location for a specific kernel ++version is: ++---- ++# dracut '' 2.6.40-1.rc5.f20 ++---- ++ ++If you want to create lighter, smaller initramfs images, you may want to specify ++the --host-only or -H option. Using this option, the resulting image will ++contain only those dracut modules, kernel modules and filesystems, which are ++needed to boot this specific machine. This has the drawback, that you can't put ++the disk on another controller or machine, and that you can't switch to another ++root filesystem, without recreating the initramfs image. The usage of the ++--host-only option is only for experts and you will have to keep the broken ++pieces. At least keep a copy of a general purpose image (and corresponding ++kernel) as a fallback to rescue your system. ++ ++=== Inspecting the Contents ++To see the contents of the image created by dracut, you can use the lsinitrd tool. ++---- ++# lsinitrd /boot/initramfs-$(uname -r).img | less ++---- ++ ++To display the contents of a file in the initramfs also use the lsinitrd tool: ++---- ++# lsinitrd /boot/initramfs-$(uname -r).img /etc/ld.so.conf ++include ld.so.conf.d/*.conf ++---- ++ ++=== Adding dracut Modules ++Some dracut modules are turned off by default and have to be activated manually. ++You can do this by adding the dracut modules to the configuration file ++_/etc/dracut.conf_ or _/etc/dracut.conf.d/myconf.conf_. See <>. ++You can also add dracut modules on the command line ++by using the -a or --add option: ++---- ++# dracut --add bootchart initramfs-bootchart.img ++---- ++ ++To see a list of available dracut modules, use the --list-modules option: ++---- ++# dracut --list-modules ++---- ++ ++or, if you have a dracut version earlier than +008+, issue the command: ++---- ++# for mod in /usr/lib/dracut/modules.d/*; do echo ${mod##*/??}; done ++---- ++ ++=== Omitting dracut Modules ++Sometimes you don't want a dracut module to be included for reasons of speed, ++size or functionality. To do this, either specify the omit_dracutmodules ++variable in the _dracut.conf_ or _/etc/dracut.conf.d/myconf.conf_ configuration ++file (see <>), or use the -o or --omit option ++on the command line: ++---- ++# dracut -o "multipath lvm" no-multipath-lvm.img ++---- ++ ++=== Adding Kernel Modules ++If you need a special kernel module in the initramfs, which is not ++automatically picked up by dracut, you have the use the --add-drivers option ++on the command line or the drivers vaiable in the _/etc/dracut.conf_ ++or _/etc/dracut.conf.d/myconf.conf_ configuration file (see <>): ++---- ++# dracut --add-drivers mymod initramfs-with-mymod.img ++---- ++ ++== Boot parameters ++The generated initramfs.img file normally does not contain any system ++configuration files (except for some special exceptions), so the configuration ++has to be done on the kernel command line. With this flexibility, you can easily ++boot from a changed root partition, without the need to recompile the initramfs ++image. So, you could completly change your root partition (move it inside a md ++raid with encryption and LVM on top), as long as you specify the correct ++filesystem LABEL or UUID on the kernel command line for your root device, dracut ++will find it and boot from it. ++ ++The kernel command line usually can be configured in _/boot/grub/grub.conf_, if ++grub is your bootloader and it also can be edited in the real boot process in ++the grub menu. ++ ++The kernel command line can also be provided by the dhcp server with the ++root-path option. See <>. ++ ++For a full reference of all kernel command line parameters, see <>. ++ ++=== Specifying the root Device ++This is the only option dracut really needs to boot from your root partition. ++Because your root partition can live in various environments, there are a lot of ++formats for the root= option. The most basic one is root=_++++_: ++---- ++root=/dev/sda2 ++---- ++ ++Because device node names can change, dependent on the drive ordering, you are ++encouraged to use the filesystem identifier (UUID) or filesystem label (LABEL) ++to specify your root partition: ++---- ++root=UUID=19e9dda3-5a38-484d-a9b0-fa6b067d0331 ++---- ++ ++or ++ ++---- ++root=LABEL=myrootpartitionlabel ++---- ++ ++To see all UUIDs or LABELs on your system, do: ++---- ++# ls -l /dev/disk/by-uuid ++---- ++ ++or ++ ++---- ++# ls -l /dev/disk/by-label ++---- ++ ++If your root partition is on the network see <>. ++ ++=== Keyboard Settings ++If you have to input passwords for encrypted disk volumes, you might want to set ++the keyboard layout and specify a display font. ++ ++A typical german kernel command would contain: ++---- ++vconsole.font=latarcyrheb-sun16 vconsole.keymap=de-latin1-nodeadkeys locale.LANG=de_DE.UTF-8 ++---- ++ ++Setting these options can override the setting stored on your system, if you use ++a modern init system, like systemd. ++ ++For dracut versions prior to version +008+ the line would look like: ++---- ++LANG=de_DE.UTF-8 SYSFONT=latarcyrheb-sun16 KEYBOARDTYPE=pc KEYTABLE=de-latin1-nodeadkeys ++---- ++ ++=== Blacklisting Kernel Modules ++Sometimes it is required to prevent the automatic kernel module loading of a ++specific kernel module. To do this, just add rd.blacklist=_++++_, with _++++_ not containing the _.ko_ ++suffix, to the kernel command line. For example: ++---- ++rd.driver.blacklist=mptsas rd.driver.blacklist=nouveau ++---- ++ ++The option can be specified multiple times on the kernel command line. ++ ++=== Speeding up the Boot Process ++If you want to speed up the boot process, you can specify as much information ++for dracut on the kernel command as possible. For example, you can tell dracut, ++that you root partition is not on a LVM volume or not on a raid partition, or ++that it lives inside a specific crypto LUKS encrypted volume. By default, dracut ++searches everywhere. A typical dracut kernel command line for a plain primary or ++logical partition would contain: ++---- ++rd.luks=0 rd.lvm=0 rd.md=0 rd.dm=0 ++---- ++ ++On systems with dracut version prior to +008+ the line would look like: ++---- ++rd_NO_LUKS rd_NO_LVM rd_NO_MD rd_NO_DM ++---- ++ ++This turns off every automatic assembly of LVM, MD raids, DM raids and crypto LUKS. ++ ++Of course, you could also omit the dracut modules in the initramfs creation ++process, but then you would lose the posibility to turn it on on demand. ++ ++ ++[[Injecting]] ++=== Injecting custom Files ++To add your own files to the initramfs image, you have several possibilities. ++ ++The --include option let you specify a source path and a target path. For example ++---- ++# dracut --include cmdline-preset /etc/cmdline initramfs-cmdline-pre.img ++---- ++will create an initramfs image, where the file cmdline-preset will be copied ++inside the initramfs to _/etc/cmdline_. --include can only be specified once. ++ ++ ++---- ++# mkdir rd.live.overlay ++# mkdir rd.live.overlay/etc ++# mkdir rd.live.overlay/etc/conf.d ++# echo "ip=auto" >> rd.live.overlay/etc/cmdline ++# echo export TESTVAR=testtest >> rd.live.overlay/etc/conf.d/testvar.conf ++# echo export TESTVAR=testtest >> rd.live.overlay/etc/conf.d/testvar.conf ++# tree rd.live.overlay/ ++rd.live.overlay/ ++└── etc ++ ├── cmdline ++ └── conf.d ++ └── testvar.conf ++# dracut --include rd.live.overlay / initramfs-rd.live.overlay.img ++---- ++ ++This will put the contents of the rd.live.overlay directory into the root of the ++initramfs image. ++ ++The --install option let you specify several files, which will get installed in ++the initramfs image at the same location, as they are present on initramfs ++creation time. ++ ++ ++---- ++# dracut --install 'strace fsck.ext3 ssh' initramfs-dbg.img ++---- ++ ++This will create an initramfs with the strace, fsck.ext3 and ssh executables, ++together with the libraries needed to start those. The --install option can be ++specified multiple times. ++ ++ ++[[NetworkBoot]] ++== Network Boot ++ ++If your root partition is on a network drive, you have to have the network ++dracut modules installed to create a network aware initramfs image. ++ ++On a Red Hat Enterprise Linux or Fedora system, this means, you have to install ++the _dracut-network_ rpm package: ++ ++ ++---- ++# yum install dracut-network ++---- ++ ++The resulting initramfs image can be served by a boot manager residing on your ++local hard drive or it can be served by a PXE/TFTP server. ++ ++How to setup your PXE/TFTP server can be found in the ++http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Storage_Administration_Guide/[Red ++Hat Enterprise Linux Storage Administration Guide]. ++ ++If you specify rd.ip=auto on the kernel command line, then dracut asks a dhcp ++server about the ip adress for the machine. The dhcp server can also serve an ++additional root-path, which will set the root device for dracut. With this ++mechanism, you have static configuration on your client machine and a ++centralized boot configuration on your TFTP/DHCP server. If you can't pass a ++kernel command line, then you can inject _/etc/cmdline_, with a method described ++in <>. ++ ++ ++ ++ ++=== Reducing the Image Size ++ ++To reduce the size of the initramfs, you should create it with by ommitting all ++dracut modules, which you know, you don't need to boot the machine. ++ ++You can also specify the exact dracut and kernel modules to produce a very tiny ++initramfs image. ++ ++For example for a NFS image, you would do: ++ ++ ++---- ++# dracut -m "nfs network base" initramfs-nfs-only.img ++---- ++ ++Then you would boot from this image with your target machine and reduce the size ++once more by creating it on the target machine with the --host-only option: ++ ++ ++---- ++# dracut -m "nfs network base" --host-only initramfs-nfs-host-only.img ++---- ++ ++This will reduce the size of the initramfs image significantly. ++ ++ ++ ++=== NFS Root Device ++ ++FIXME ++ ++=== iSCSI Root Device ++ ++FIXME ++ ++=== FCoE Root Device ++ ++FIXME ++ ++== Troubleshooting ++ ++If the boot process does not succeed, you have several options to debug the ++situation. Some of the basic operations are covered here.

Remove ''rhgb'' and ''quiet'' from the kernel command line ++. Add ''rd.shell'' to the kernel command line. This will present a shell should ++dracut be unable to locate your root device ++.

The required steps will depend on how your ++root volume is configured. Common scenarios include: ++ ++* A block device (e.g. _/dev/sda7_) ++* A LVM logical volume (e.g. _/dev/VolGroup00/LogVol00_) ++* An encrypted device (e.g. _/dev/mapper/luks-4d5972ea-901c-4584-bd75-1da802417d83_) ++* A network attached device (e.g. netroot=iscsi:@192.168.0.4::3260::iqn.2009-02.org.fedoraproject:for.all) ++ ++The exact method for locating and preparing will vary. However, to continue with ++a successful boot, the objective is to locate your root volume and create a ++symlink _/dev/root_ which points to the file system. For example, the following ++example demonstrates accessing and booting a root volume that is an encrypted ++LVM Logical volume. ++ ++. Inspect your partitions using parted +++ ++---- ++# parted /dev/sda -s p ++Model: ATA HTS541060G9AT00 (scsi) ++Disk /dev/sda: 60.0GB ++Sector size (logical/physical): 512B/512B ++Partition Table: msdos ++Number Start End Size Type File system Flags ++1 32.3kB 10.8GB 107MB primary ext4 boot ++2 10.8GB 55.6GB 44.7GB logical lvm ++---- +++ ++.

All ++modules are located in _/usr/lib/dracut/modules.d_ or in _/modules.d_. ++The most basic dracut module is _99base_. In _99base_ the initial shell script ++init is defined, which gets run by the kernel after initramfs loading. Although ++you can replace init with your own version of _99base_, this is not encouraged. ++Instead you should use, if possible, the hooks of dracut. All hooks, and the ++point of time in which they are executed, are described in <>. ++ ++The main script, which creates the initramfs is dracut itsself. It parses all ++arguments and sets up the directory, in which everything is installed. It then ++executes all check, install, installkernel scripts found in the modules, which ++are to be processed. After everything is installed, the install directory is ++archived and compressed to the final initramfs image. All helper functions used ++by check, install and installkernel are found in in the file _dracut-functions_. ++These shell functions are available to all module installer (install, ++installkernel) scripts, without the need to source _dracut-functions_. ++ ++A module can check the preconditions for install and installkernel with the ++check script. Also dependencies can be expressed with check. If a module passed ++check, install and installkernel will be called to install all of the necessary ++files for the module. To split between kernel and non-kernel parts of the ++installation, all kernel module related parts have to be in installkernel. All ++other files found in a module directory are module specific and mostly are hook ++scripts and udev rules. ++ ++ ++[[stages]] ++== Boot Process Stages ++ ++The init script in _99base_ is the main script, which prepares the root file ++system for usage, runs udev, mounts the real root device, kills the remaining ++processes, and switches to the real root device for further booting. dracut ++modules can insert custom script at various points, to control the boot process. ++These hooks are plain directories containing shell scripts ending with ".sh", ++which are sourced by init. ++Common used functions are in _dracut-lib.sh_, which can be sourced by any script. ++ ++ ++ ++=== Basic Setup ++ ++The first thing init does, is to mount _/proc_ and _/sys_ and manually create ++the basic device nodes and symbolic links in _/dev_ needed to execute basic ++commands. Then logging is setup according to kernel command line arguments. ++_/dev/pts_ and _/dev/shm_ are mounted and the first hook is sourced. ++ ++ ++ ++=== Hook: cmdline ++ ++The _cmdline_ hook is a place to insert scripts to parse the kernel command line ++and prepare the later actions, like setting up udev rules and configuration ++files. ++ ++In this hook the most important environment variable is defined: root. The ++second one is rootok, which indicates, that a module claimed to be able to parse ++the root defined. So for example, **root=**__iscsi:....__ will be claimed by the ++iscsi dracut module, which then sets rootok. ++ ++=== Hook: pre-udev ++ ++This hook is executed right after the cmdline hook and a check if root and ++rootok were set. Here modules can take action with the final root, and before ++udev has been run. ++ ++ ++ ++=== Start Udev ++ ++Now udev is started and the logging for udev is setup. ++ ++ ++ ++=== Hook: pre-trigger ++ ++In this hook, you can set udev environment variables with **udevadm control ++--property=KEY=_value_** or control the further execution of udev with ++udevadm. ++ ++ ++ ++=== Trigger Udev ++ ++udev is triggered by calling udevadm trigger, which sends add events for all ++devices and subsystems. ++ ++ ++ ++=== Main Loop ++ ++Now the main loop of 99base/init begins. Here we loop until udev has settled and ++all scripts in _initqueue/finished_ returned true. In this loop there are three ++hooks, where scripts can be inserted by calling /sbin/initqueue. ++ ++ ++ ++==== Initqueue ++ ++This hook gets executed every time a script is inserted here, regardless of the ++udev state. ++ ++ ++ ++==== Initqueue settled ++ ++This hooks gets executed every time udev has settled. ++ ++ ++ ++==== Initqueue timeout ++ ++This hooks gets executed, when the main loop counter becomes half of the ++rd.retry counter. ++ ++ ++ ++==== Initqueue finished ++ ++This hook is called after udev has settled and if all scripts herein return 0 ++the main loop will be ended. ++ ++ ++ ++=== Hook: pre-mount ++ ++Before the root device is mounted all scripts in the hook pre-mount are ++executed. In some cases (e.g. NFS) the real root device is already mounted, ++though. ++ ++ ++ ++=== Hook: mount ++ ++This hook is mainly to mount the real root device. ++ ++ ++ ++=== Hook: pre-pivot ++ ++This hook is the last hook and is called before init finally switches root to ++the real root device. This is a good place to clean up and kill processes not ++needed anymore. ++ ++ ++ ++=== Cleanup and switch_root ++ ++Init kills all udev processes, cleans up the environment, sets up the arguments ++for the real init process and finally calls switch_root. switch_root removes the ++whole filesystem hierarchy of the initramfs, chroot()s to the real root device ++and calls /sbin/init with the specified arguments. ++ ++To ensure all files in the initramfs hierarchy can be removed, all processes ++still running from the initramfs should not have any open file descriptors left. ++ ++ ++ ++== Network Infrastructure ++ ++ ++FIXME ++ ++ ++== Writing a Module ++ ++A simple example module is _96insmodpost_, which modprobes a kernel module after ++udev has settled and the basic device drivers have been loaded. ++ ++All module installation information is in the file module-setup.sh. ++ ++First we create a check() function, which just exits with 0 indicating that this ++module should be included by default. ++ ++check(): ++ ++ ++---- ++return 0 ++---- ++ ++The we create the install() function, which installs a cmdline hook with ++priority number 20 called _parse-insmodpost.sh_.

The root device should better be identified by LABEL or UUID. If a ++label is used, as in _root=LABEL=_ the initramfs will search all ++available devices for a filesystem with the appropriate label, and mount that ++device as the root filesystem. _root=UUID=_ will mount the partition ++with that UUID as the root filesystem. ++ ++In the following all kernel command line parameters, which are processed by ++dracut, are described. ++ ++"rd.*" parameters mentioned without "=" are boolean parameters. They can be ++turned on/off by setting them to {0|1}. If the assignment with "=" is missing ++"=1" is implied. For example _rd.info_ can be turned off with _rd.info=0_ or ++turned on with _rd.info=1_ or _rd.info_. The last value in the kernel command ++line is the value, which is honored. ++ ++Standard ++~~~~~~~~ ++**init=**__:: ++ specify the path to the init programm to be started after the initramfs has ++ finished ++ ++**root=**__:: ++ specify the block device to use as the root filesystem. +++ ++E.g.: +++ ++---- ++root=/dev/sda1 ++root=/dev/disk/by-path/pci-0000:00:1f.1-scsi-0:0:1:0-part1 ++root=/dev/disk/by-label/Root ++root=LABEL=Root ++root=/dev/disk/by-uuid/3f5ad593-4546-4a94-a374-bcfb68aa11f7 ++root=UUID=3f5ad593-4546-4a94-a374-bcfb68aa11f7 ++---- ++ ++**rootfstype=**__:: "auto" if not specified, e.g.: +++ ++---- ++rootfstype=ext3 ++---- ++ ++**rootflags=**__:: ++ specify additional mount options for the root filesystem.
